In the drawings, Fi ure 1 is a perspective view of my binder, s owing ,anumber of sheets or folios in position. Fig. 2 is a sectionalperspective through the middle'of one of my composite binding-tabs,showing it applied to a combination of folio and single sheets,fragments of which are shown in section. Fig. 3 is a perspective view ofone of my binding-tabs. Fig. 4 is a perspective view showing thecomplete invention with the flexible covers reversely folded and securedfor easy transportation.

5 is a cover, of some durable material, comprising broad sides, acentral back, and intermediate hinge-like connecting portions 20, eachhaving punched in it perforations 6, with eyelets for the assage of thewire,

ii secures the tabs on which the various sheets or combinations ofsheets, folios, &c., 8 are threaded.

9 9 are gummed tabs, which are made of two or more (preferably three)superposed leaves 10 11 12,of linen or other strong flexible materialgummed on one side and all fastened together at oneend by a centraleyelet 13, through which eyelet passes the tempo-I rary-binding cord 7,connecting the folios to the back or cover, as before mentioned. The twooutside leaves of the tab are preferably gummed on their inner surfaces,the rest on either side, at will, and, having the stiffness peculiar togummed linen, they may be readily introduced separately and endwisethrough slits formed at the fold of sheetmusic'and the like. It will benoticed as a special advantage of this tab, with ,a plurality of thesesuperposed leaves eyeleted together compressibly at one end, that eachleaf has an adhesive surface of the full width of the en-' tire tab andabundant strength to connect Specification of Letters Patent.Application filed ti e z aoaf s mi No. 170,864.

the-sheets or folios to each other and to the coverand that since theeyelet 13 is located in the transverse center line the strain of use isin' thc'direct plane of the perforation or eyeletandequallyon each sideof said plane. .7 On'eXamination of Fig. 2 it is'clear that with three'leavesto thetab any of the following combinations of sheets can besecured to the tab alid monnted for binding: first, three loose sheets,as 14 15 16, each gummed to a separate leaf of the tab; second, threeloo'se sheets, as 14 15 16, with any number of folios 17 by makingincisions in the folds of the several folios for the passage of the leaf11 of tab 9, which is then gummed to the loose leaf within the innermostfolio third, two loose sheets, as 14 16, and any number of folios 17 bymakingincisions, as abov described, in all the folios except the innerone and adhering leaf 11' to the outside of'either one of the leaves ofthis folio, according to which side of leaf 11 is gummed fourth, anynumber of folios 17 with or without a central single sheet 15. Thesetabs are'spaced according to the spacing of-eyelets 6 in the cover, twobein sufficient if all the sheets are of one size, alt ough any numbermay be used, thus enabling me to bind into the same ,cover sheets ofvarying sizes. A pair of these composite tabs without a. cover willserve efliciently to bind together a number of distinct sheets.-suchasengravings, mounted photographs, &c.since the broad strong flexibleleaves well gummed and firmly united by the eyelet form sufficienthinges for the single sheets, connecting them in a series.

By makin the covers of my binder flexible I can form t e whole'into aroll suitable for carrying and without removing any of the sheets. i Themethod of folding is shown in Fig. 4 and consists in folding allthesheets or follos 8 and one cover B in one-direction and then foldingover these the other cover A in the opposite direction, thus making adouble thickness of flexible cover outside. The two covers are thenfastened to each other to secure them in this folded superposed positionby any suitable means, as by snaps 18 18, consisting of the usual studand circular caip handle L9 may be provided for eater facil ity ofcarriage. I apply this met 0d of forming a portable roll to a set ofsheets, folios, or signatures, which are or may be permanently boundwithin flexible covers.

I claim as my invention-- 1. The composite tab described, composed ofthree superposed leaves of gummed textile fabric, permanently united atone end by a centrally-arranged eyelet, the two outer leaves beinggummed on 0p osite surfaces and adapted at their free en s to adhere tothe outer sheets of a'folio, the free endof the central leaf being ofsuitable stiffness and adapted for insertion through'a slit in thefolded edge of said folio, for the purpose of adhesion to a centralsheet, whereby intermediate folios may be held in place, substantiallyasset forth.

2. A carrying device for sheet-music or other folios, comprising aflexible cover, composite tabs suitably secured to said cover and avinggummed leaves each adapted for adhesion to a separate sheet or folio,and fastening devices applied to the flexible covers, in position toengage and disengage repeatedly whenone cover is folded with the sheets2 5 or folios in one direction, and the other cover is folded over themin the opposite direction, substantially as set forth.

3. The combination of an inclosing cover adapted to receive a number. ofsheets or folios to be bound into said cover, and gummed tabs eachconsisting of a plurality of superposed leaves permanently fastenedtogether at one end by a centrally-arranged eyelet, each of said leavesbeing ada ted to adhere at its free end to a sheet or f0 i0, the foldededge of said folio being provided with slits for the passage through thesame of some of said leaves, and means for securing said tabs to saidcover, substantially as set 40 forth. i

In testimony whereof I have affixed my signature in presence of twowitnesses.
